How can I let Tika know the resource name?

[122jxgcn <yw...@gmail.com>]

Hello,

I'm using Solr's ExtractingRequestHandler to let Tika know the name of the
file when indexing.
I'm currently sending HTTP request something like

/update/extract?stream.file=#{filepath}&literal.id=#{filepath}&resource.name=#{resource_name}&commit=true

Will setting the resource.name variable let Tika know the name of the file 
so that it can determine Metadata of the file properly?
(for example resource_name = "file.custom" then in Tika, 
Metadata.RESOURCE_NAME_KEY becomes "file.custom")
I'm not sure how can I test this so I'm confused.

Thank you.

If you pass the resource name as you are doing in it will be fed into Tika and used as a hint for Mime Type detection.  I assume it was Mime Type detection you were looking for.

The best way to see what is happening around metadata - and if what you were trying to pass has made it - is to look at the results of what happens in Extract Only mode[1].
